description

A good part of what has been collected here appears to be material for a report or reports to the Coast and Geodetic Survey. Included are notes to superiors and subordinates in the Survey a description of the Gravitation and Astronomical Station, Ebensburg, Cambria Co., Pennsylvania pendulum readings at the Smithsorlian and in Ann Arbor, Ithaca, and Madison calculation for Gautier pendulums the comparison of a metal decimetre with a glass decimetre notes on a clock signal and self-switch list of books and apparatus charged to CSP corrections to Appendices 15 and 16 of the Report of 1884. Approximately one-hundred-fifty leaves with red and blue numbers serawled on one side have been separated from the rest. These constitute a miscellaneous collection of worksheets, numbered by CSP in red from 1 to 2038 and in blue from 2038 to 1 (i.e., red number 1 is blue number 2038). Included here are records of pendulum observations for the Coast and Geodetic Survey, calculations, exploration of mathematical problems.
